To all whom t may concern:

Be it known that I, JAMES WHITELAW, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented a certain newand useful Improvement in Engines, of which the following is a description, reference being had to the accompanying drawings, forming part of this speciiication.

My invention has for its object the production of a small and compact high-speed engine of maximum power in proportion to its size and weight, and adapted more particularly for use as the engine or motor part of light, portable, manually-handled rotary tools of various characters, such as drills, {lue-cutters and rollers, and the like. lts novelty' consists in the various features of consti-notion, arrangement and combination of parts by which this object is attained; also in novel and simple mea-ns for reversing the engine at will, and for changing the speed of the tool without changing the speed of the engine; all as hereinafter more fully explained. Y

ln the accompanying' drawings my invention has been illustrated as embodied in a rotary drill, and in said drawings Figure 1 represents what may be termed a front elevation of the machine, with the lower part of the casing removed to expose the gearing through which the tool-shaft -is driven from the engineshaft; Fig. la a longitudinal section through the left-hand one of the two handles shown in Fig. 1, illustrating the throttle-valve for controlling the inlet of the motive fluid, and the reversing gear; Fig. 1b a sectional detail on the line lb-lb of Fig. 1, showing the reversing slide and the rack and gear for operating it in elevation; Fig. 2 a vertical section, partly in the plane indicated by the dotted line 2 2 on Fig. 1 and partly in the plane indicated by the dotted line -m on Fig. 1, the former being a middle vertical section through the toolshaft and three members of the train of gearing, and the latter a section throu h theaxis of oscillation of the cylinders; ig. 2 a horizontal section approximately on@ the line 2aa of Fig. 1, with the rear portion of the gear casing broken away and the front portion in place; Fig. 3 an enlarged ving in detail front view of the machine, with the forward side of the casing andthe parts carried by it removed, to expose the cylinders and crank-shaft within the casing; Fig. 4 a vertical Section approximately on the line 4 4 of Fig. 3; Fig. 5 a corresponding view on the line 5-5 of Fig. 3.

The saine letters-ofreference are used to indicate corresponding parts in all the views.

The cylinders and the engine-shaft or crank-shaft are inclosed within a casing A of suitable shape, While a'supplemental casing A partly shown in Fig. 2 incloses the train of gearing at the bottom of the casing A. Journaled at its opposite ends in bearings in the casingA, Fig. 3, is a double crank-shaft B to whose cranks are 'connected the piston-rods C C of a pair ofl oscillating engines D D whose trunnions are journaled at their outer ends in bearings in thecasing A and at their inner ends in bearings in a support E projecting upward or forward. from the casing A betweenthe two engines, Figs. 2, 4, and 5.

The crank-shaft B and the trunnions of the enginesare journaled in ball-bearings,

the balls being confined in cups or hous.

ings F screwed into the casing A and support E as shown in Figs. 2 and 3. u

Steam is admitted to the engines through a tubular handle G, Fig. 1, which handle has connected to its left hand end a flexible hose H leading to the motive fluid. supply.V At its right hand end the tubular handle G is screwed into a slide I Vconlin'ed in guideways-upon the left hand side of the cas- Figs. l and 3 and adapted to be slid hackwardly and forwardly therein. The

handle G and its connection with the slide I are shown in fsection in Figs. 1a and 5.

`For1ned integral with the slide I is an 'in-` wardly extending curved yoke J, which is hollow and whose internal passage forms a continuation of the passage in the handle G, Fig. 5. This hollow yoke J extends over and around the middle support E between the two engines, and down between said engines at its opposite ends in position for ports K K formed in its opposite 'sides at its opposite ends to vcoperate with ports -L L formed in the side .walls of the engine .cylinders'at the `op1,r ;.osite ends of the latter; The adjacent surfaces of the engine cylinders` and yoke J at the ports mene tioned` are properly, shaped and finished to t snugly together and form coperating valve faces. v l

. Under this construction and arrangement of the parts the admission of motive fluid through/the handle Gr and hollow `yoke J will serve to drive the engines in the usual manner. In Fig. 4 the engine D is taking. motive duid at its left hand end, while its .right hand end is openv to the exhaust', so'

' that the engine shaft is being driven in the direction of the arrow. It will be observed, however, that if the yoke J should be moved upward (in Fig. 4) until the ports K L were carried out of register and the ports f K L brought `into register and motive iuid thereby admittedto the port L" the piston will be driven toward the left, instead of toward the right, and the-direction of motion of the engine be reversed. This very simple method .of reversing the engine is provided for by the adjustment of the slide I in its guideways upon the casing A. As 'shown in the various views of the drawx'ings 'the slide I is in what may be termed its rearward position, h'aving reference to Figs.

lland 3; but if it be slid forward (upward in' Figs'. 4 and 5) the yoke J will be carried i forward or upward, with the result of reversing the direction of motion of the engines, as will bev readily understood. Any

suitable means for shifting the slide I for this purpose may-be employed without departing from this feature of my invention. yI have illustrated one' convenientform of against the slide'I' and has formed upon its one side gear teeth' a meshing with the rack a, and on its opposite side two projecting teeth c' at some'distance apart, adapted to cooperate with the notches b in the plate N. A coiled spring d surrounding vthe tubular handle G within the sleeve 0 and bearing at one end against an internal shoulder on said sleeve and at its opposite end against s .a collar e ,fast yupon ,the handle, Fig. 1,

'i permits it to be slid tothe left `against the resistance of such spring, a flange upon the presses the sleeve k0 toward the right, but

collar e limiting 'its movement in the latter direction. When 'the gear teeth a' on the sleeve O are engaged with the rack a on the plate M,l and one of theteeth c on' the op.- posite side ofthe sleeve engaged with one of the notches b inthe'lplate N, the sleeve O will be locked from rotation, and the slide I likewise locked in'I fixed, osition in its guideway. By "sliding the's eeve O to the left to its limitpf movement, however, its

tooth c will be disengaged from the notch in the plate N, without disengagin its gear teeth a from the rack of the plate (owing to the fact that the plate .M and rack are considerably thicker than the plate N, as shown), and when so disengaged the sleeve .O may be turnedupon the tubular handle G. When so turned vits gear a will roll along the rack a of the plate M and move th'e'slide I along its guideway in the corre spending direction. Thus, in Fig. lb the turning of the sleeve 0 in the direction of the arrow will raise the slide I, and when it has reached its limit of movement the lower tooth c on the sleeve O will be brought opposite the uppernotch b in the plate M, and

upon then releasing the sleeve 0 the coiled spring will force it to the right against the slide I and engage said tooth and notch, and thereby lock the parts in such position.

` This shifting of the slide I will reverse the engine in the manner before explained.

The throttle-valve P for controlling the supplyv of motive fluid is located in and upon the tubular handle G a short distance to the left of the sleeve O, so that the operator may at any time readily slip his left hand from lone to the other, turning the throttle-valve to 'eut off the motive fluid supply, then turning the sleeve O to reverse the engine, and then turning the throttle-valve'back to admit the motive fluid. The lthrottle-valve P illustra-ted in the drawings is, in its general construction, of old and well-known form, and 'need not be described further than to say that by turning the outer sleeve of the valve to one position communication between the passages entering the opposite ends of the valve is' cut oil", and by turning the sleeve to its opposite position such communication is restablished. v

Secured to the opposite side ofthe casing A is another handle G', which in the present instance is also hollow or tubular and constitutes one of the exhaust openings from the casing A.

Havin now described the engine or motor proper ot the machine, it remains to explain the train of gearing by which its power is transmitted to the tool-shaft. As shown in Fig. 3, the engine-shaft B has secured upon its lower end, beneath the main casing A, a pinion Q, meshes with a gear wheel R mounted on a stub-shaft or spindle S secured in and depending rom one end of a lever T fulcrumed upon the'bottom ofthe casingA at U. The gear R has fast upon its upper side a pinion which pinion, as shown in Fig. 2,
